Make peaceful, expansion, starting area, pollution, etc. planet specific

One of the first things that bothered me with Space Age a year ago was that it is not possible to turn off pollution on Nauvis while leaving it on for Gleba. Or make my starting area on Nauvis 2 while keeping it 1 on Vulcanus. Each of the advanced settings should be able to be set on a per planetary surface basis.

As I understand the surface generation features, it seems to already have these settings on a per surface basis. This means that only the freeplay UI to control how they are set has to be reworked. It does seems like a significant amount of work to add, but as the addition of new features to Factorio is near its end, this seems like on of those final polish features that should be on the list.
